Description

Technical Field

[0001] This utility model relates to the field of building construction tools, and in particular to a tool for improving the quality of mortar joints in masonry construction. Background Technology

[0002] Mortar joints in masonry construction are a crucial part of the masonry project. They refer to the joint lines formed between bricks after they are bonded together with mortar during the construction of a wall. Mortar joints are mainly divided into horizontal mortar joints and vertical mortar joints. Horizontal mortar joints are the joints between the upper and lower layers of bricks, while vertical mortar joints are the joints between adjacent bricks.

[0003] In existing masonry construction, it is necessary to control the thickness of horizontal mortar joints. Currently, the common method for controlling the thickness of horizontal mortar joints is to use a horizontal line. However, this method is prone to problems, as it is unclear whether the line is perfectly horizontal or tilted, making it difficult to control the thickness of the mortar joints evenly. Furthermore, this method consumes considerable laying time. In addition, the horizontal line cannot be used for every layer of masonry; it can only be used within a certain height, with the top of the line aligned with the horizontal line. As a result, the thickness of the mortar joints within each layer within that height cannot be effectively guaranteed, thus affecting the construction quality. Therefore, a tool is needed to improve the quality of mortar joints in masonry construction to solve the above problems. Utility Model Content

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0022] like Figures 1 to 4As shown, a tool for improving the quality of mortar joints in masonry construction includes two L-shaped fitting and limiting frames 1. Each fitting and limiting frame 1 has a baffle 2 fixedly connected to one side of its opposite side. The length of the baffle 2 is less than the length of the fitting and limiting frame 1. A first connecting groove 3 is provided on one side of each baffle 2. Several interconnected extended baffle structures 4 are provided on each baffle 2. Mounting plates 5 are fixedly connected to the top sides of the two uppermost extended baffle structures 4. Clamping devices are slidably connected to one side of each mounting plate 5. The outer surfaces of the two clamping rods 6 are threaded with two wing-shaped clamping nuts 7. The wing-shaped clamping nuts 7 and the clamping rods 6 allow the extension baffle structure 4 to move the baffle 2 and the fitting limiting frame 1, thus enabling the fitting limiting frame 1 to fit against the brickwork. A scraper structure 8 is provided on each of the two mounting plates 5. Several positioning plates 9 are slidably connected to one side of each of the two fitting limiting frames 1. Several first adjustment holes 10 are provided on one side of each of the positioning plates 9. The inner wall of 0 is threaded with adjusting bolts 11. Several second adjusting holes 12 are provided on one side of each of the two fitting limiting frames 1. The extension baffle structure 4 can be fixed via the positioning plate 9, the first adjusting hole 10, the adjusting bolts 11, and the second adjusting holes 12, ensuring the connection stability between multiple extension baffle structures 4. When it is necessary to construct mortar joints in the masonry, first select an appropriate number of extension baffle structures 4 and connect them together. Then, connect the extension baffle structures 4 with the baffle... The plates 2 are connected, and then the bottom side of the baffle 2 is overlapped on the brick, so that the fitting limiting frame 1 is in contact with the brick. Then, the butterfly locking nut 7 is rotated to make it fit tightly with the mounting plate 5. At this time, the brick is located inside the two fitting limiting frames 1. Then, the mortar used for masonry joints can be placed inside the area formed by the two baffles 2 and multiple extended baffle structures 4, so that the upper surface of the mortar used for masonry joints is on the same horizontal plane as the upper surface of the uppermost extended baffle structure 4, thereby masonry joints of a specific thickness.

[0023] As an optional technical solution of this utility model, the extension baffle structure 4 includes an extension baffle 401, a first connecting block 402, a second connecting slot 403, and a third adjusting hole 404.

Several third adjusting holes 404 are opened on the side of the extension baffle 401 adjacent to the second connecting slot 403. When connecting two extension baffle structures 4, the first connecting block 402 on one extension baffle 401 is inserted into the second connecting slot 403 on the other extension baffle 401, and then the positioning plate 9 can be moved. Then, select an appropriate number of adjusting bolts 11, connect one adjusting bolt 11 to the first adjusting socket 10 and the second adjusting socket 12, thereby connecting the positioning plate 9 and the fitting limit frame 1. Then, connect the adjusting bolt 11 to the first adjusting socket 10 and the third adjusting socket 404, thereby connecting the positioning plate 9 and the extension baffle 401, and fixing the extension baffle 401. In practical applications, the thickness of the mortar joint of masonry is generally 8-12mm. When making this tool, the height of the baffle 2 is set to 7mm, and the thickness of the extension baffle 401 is set to 1mm, so that the tool can perform masonry operations with 8-12mm masonry mortar joints.

[0024] As an optional technical solution of this utility model, the scraper structure 8 includes a through groove 801, a sliding rod 802, a limiting nut 803, a mounting sleeve 804, a handle 805, and a scraper 806.

Two limiting nuts 803 are threaded onto the outer surface of the sliding rod 802. The limiting nuts 803 are fitted against one side of the mounting plate 5, and the two limiting nuts 803 can control the sliding rod 802. To limit the sliding rod 802 and prevent it from shifting left or right, a mounting sleeve 804 is fitted onto the outer surface of the sliding rod 802. A handle 805 and a scraper 806 are fixedly connected to the outer surface of the mounting sleeve 804. After the mortar for the masonry joint is placed inside the area formed by the two baffles 2, if the height of the mortar is higher than the upper surface of the extended baffle structure 4, the mounting sleeve 804 can be moved by the handle 805 to move the sliding rod 802. At this time, the scraper 806 moves accordingly and scrapes off the excess mortar.

[0025] As an optional technical solution of this utility model, the first connecting block 402, the second connecting slot 403 and the first connecting slot 3 are all dovetail-shaped. The positions of the first connecting block 402 and the second connecting slot 403 are corresponding, the sizes of the first connecting block 402 and the second connecting slot 403 are compatible, and the sizes of the first connecting block 402 and the first connecting slot 3 are compatible. The connection between the extension baffle 401 and the baffle 2 is relatively firm through the first connecting block 402 and the second connecting slot 403. The connection between the two extension baffles 401 is relatively firm through the first connecting block 402 and the second connecting slot 403.

[0026] As an optional technical solution of this utility model, the size of the first adjustment socket 10 and the second adjustment socket 12 are adapted to each other, and the size of the adjustment bolt 11 is adapted to the first adjustment socket 10, so that the adjustment bolt 11 can be smoothly connected to the first adjustment socket 10 and the second adjustment socket 12.

[0027] As an optional technical solution of this utility model, the length of the baffle 2 is adapted to the length of the extended baffle 401, the width of the baffle 2 is adapted to the width of the extended baffle 401, and the length of the baffle 2 is greater than the thickness of the extended baffle 401.

[0028] As an optional technical solution of this utility model, the scraper 806 is attached to the top side of the extension baffle 401. The length of the scraper 806 is greater than the minimum distance between the two baffles 2 and less than the minimum distance between the two mounting plates 5, so that the scraper 806 can move smoothly and scrape the mortar between the two baffles 2.
